Opinions of what to do

[T206Collector]

The SGC holder doesn't help the image. If you look at the bottom left corner you can also see how the cut out corner of the holder makes it look like the card's corner is bigger or something "askew."

I am fairly sure the card was damaged in the ordinary course of its 100 year life, but like BigFanNY said, if you don't like the card send it back or resell it. I, too, get fixated on blemishes sometimes that make me hate the card. No reason to keep those and try to convince yourself you're over-reacting.

No visible hint of a repair on the back side....Im guessing this one is graded correctly and SGC would confirm their opinion on it. Having said that - Wow tuff set...eBay shows a grand total of 37 of these and NONE are inexpensive. Never even new these existed until today.

I think it is graded correctly and that upper corner issue could be from being in an album, with those little things that keep the corners in (hinges?).

If possible, instead of the entire card, can you post a scan, a large scan (hopefully hi-res), of just the area in question? That would allow the people here who could really help you out to offer an even more educated and insightful assessment.
